To all whom it may concern:

Be it known that I, WLADYSLAW MAJEW- sin, a subject of the Czarof Russia, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Rotary Compression- Machines, of which the following is a specification.

This. invention relates to machines for the compression of plastic materials into bricks, briquets and the like, of the type comprising a rotary drum having radial chambers into which charges of plasticimaterial are successively introduced, radially reciprocated plungers in said chambers, actuated by a central cam or cams, and anabutment between which and the said plungers the charges are compressed, said compressed charges "being ultimately expelled on to a traveling belt or conv'eyer.

The object of this invention is to effect improvements in this type of machine in regard to the actuation of the plungers, whereby positive retraction and expulsion are obtained and the use of retractively opobviated, in regard to the.

crating springs is adjustment of the plungers within the chambers for the regulation of the amount of material received in each, and in regard to the abutment and its operation.

It also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure l is an ex'terior'end view of my device.

Fig. 2 is a vertical section transverse to the axis of the machine.

Fig. 3 is a sectional view on lines 33 of Fig. 1. y I V Fig. 4: is a perspective view of a part, showing the plunger and means for regulating the amount 0i material received in the molds. r

Fig.5 is a part sectional View of the same. Fig. 6 isa diagrammatic view of the-cams. As shown in the present drawings, is a rotatable, hollow drum, having in its wall a plurality of radial apertures 2 forming compression chambers which may be arranged in longitudinal. rows, so disposed that each in succession may be filled with plastic material from a hopper or chute 3. The axis of the drum is mounted at each end in suitable bearings, as at 4, and has at the ends spur wheels 5, through which power is transmitted from a pinion '6 and worm gear 7, or other equivalent or'suitable de' 'vice by which motion is transmitted torotate the drum.

fitted in each of the radial compression chambers and is withdrawn so as to receive a charge of plastic material when passing the supply hopper, and is afterward .forced outward A plunger 8 is slidably to compress the mass during the subsequent revolution of the drum. The means for operating the plungers consists of irregular,

cams 9 and 10,-one of which is located within the other, and about the center of the hollow drum through which the plun-- gers are caused to reciprocate by the action I of these cams. 13 which. travel upon the surface of the cam 10 to force them outward to compress the charges received in the chambers 2.

The inner ends of the plungers are tapered,

interiorly to the shoulders-13, and may be rounded or'otherwise for rned, asshown at 11, so that these ends traveling againstthe surface of the inner cams will control the inward movements of the plungers to follow the contours of the cams 9 and 10, when retracted.

Each of these inner ends has a pin 12 passing through it and adapted to move between the inturned flanges of the inner pe riphery of the cam 10 and the outer surface of the earn 9 to guide the plunger movements in reciprocating; and also to regulate the charge in each plunger chamber, as hereafter described. v

The plastic material which is being operated upon maybe of different qualities of plasticity, and in order to regulate the amount of each plunger chain-her, I show a means for adjusting these plungers for a greater or less amount of material to be received. As shown in- Figs. 4 and 5, these plungers have narrow extensions whichpass between the flanges of thecompression cam 10, which pression in the formation of the bricks,

The plungers have shoulders material which is admitted into' shoulders serve to receivethe thrust of com- The inner ends" of the plunger extensionsare received in the head of a radially adjustable member 14, the latter having an inwardly extending shank 15, which has a V-shaped notch 16 formed in one side of it.

Upon a shaft 17, journaled "in the cam 9 contiguous to the extension 12''), formed a projection or cam 18 which is adapted to enter and coact with the groove 16, so that The movement of the shank 15, actuated by I the adjusting cam 18, controls the amount of mate ial admitted to the plunger chamber.

The opposing or compression surface consists of-aseries of compression plates 19,

which are connected together by links 20, so

as to form an endless chain; the links being of such a length that the plates 19 will be brought to register with the chambers 2, after the latter have been filled with the plastic material. In order to direct these plates properly, I have shown a segment 21, so mounted with relation to the drum and the plunger chambers that its interior curvature forms a support for the plungers, which plungers are in register with the plunger chambers while the plungers are being moved outwardly to compress the brick, as plainly shown in Fig. 2.

The links carrying the plates 19 and their connections are here shown as made convex,

.and the ends at which the links are connected are provided with rollers 21 so that when, during the revolution of the drum, the plates are brought to register with the plunger chambers, these rollers will travel against the interior of the segment and will thus prevent undue friction during the passa e.

It will be understbod that any equivalent form of support, between which and the drum the compression plates may pass, will similarly act to resist the outward force of the plungers as effected by the action of the interior cams, and that in this manner each brick will be properly compressed, and preferably by the-continued action of the cams while the bricks are passing through thecompression mechanism.

When the bricks have been fully compressed, the plungers are caused to move outwardly by contact with the outer surface of theinner cam which then forces them out after leaving the compression element 21, and

with them the bricks which may be delivered upon a suitable carrying belt 22, which is mounted to travel upon drums 23journaled in proper proximity with the plunger-carrying drum. When the drum is rotated to a point where the bricks have been delivered and the plungers are at their extreme out ward movement, the outer cam 10, acting upon the pin 12, will commenceto retract the plungers; and when the plunger chambers have again begun to register with the feed hopper 3 the plungers will be retracted so as to receive the required amount of plastic material, this amount being regulated, as previously described, by the adjustment caused by the notched shank 15 and the engaging cam 18.

In order to properly direct the plastic material into the chambers I have shown divergent hoods 24, located in the feed hoppersand so placed that the plastic material pass ng over these hoods will be directed into the plunger chambers.

Having thus described my invention,

what I claim and desire to secure by Letters Patent is-- 1. In combination with a drum having radial compression chambers and reciprocat ing plungers therein, an inner cam, an outer cam spaced from the inner cam, said cams having a radial cut-out, a rigidly formed member slidable in the cut-out and having a face corresponding to the inner cam and v i spaced side flanges overlying said face and corresponding to the outer cam, said plungers having their inner ends formed to be received in the space between the flanges of said member and to directly engage said inner cam and said faceof said member," pins on the plungers engaging the flanges of said members and the-outer cam", shoul-' ders on the plungers, said outer cam havin f a bulged part to engage said shoulders to e fect the compressing movements of the plungers, said member having a notch in a side thereof, a shaft journaled .in the innen cam, and a projection on the shaft engaged in said notch to effect sliding of-said member.
